The CAT 6000 should be able to handle this, the Router PAM supports two
PA's. You'll only be using a single PA for the OC-3 interface. ATM to Frame
Relay (FRASI) is handled by the service provider. MCI will supply you with
VPI/VCI numbers that map to DLCI's on the far end. I would definately look
into ODR, with the newer 12.0.5T or higher code. I would have a Cisco
Engineer confirm that it will work with the CAT 6000 series. ODR will supply
a default route to the far end, and add the addresses to the local routing
table. You can take a look at inARP and other things that will allow you to
send out the routers without any configuration required for the far end.
Thus, all configs are done at the central office, making it so that you can
keep a warm spare on standby ready to go anywhere.
